菏泽5.9级地震前后沂水泉氡区间概率的变化
|
摘要
影响沂水泉氡值变化最大的干扰是降雨。因为这种干扰存在着“记忆”滞后影响 ,所以用一般的相关分析难以将这种影响排除干净。研究表明采用褶积积分方法可较好地排除这种影响 ,同时分析了菏泽 5 .9级地震前后沂水泉氡区间概率的变化特点 ,讨论了区间概率的变化与区域应力场的调整变化的关系
Many years of observation and analysis for radon in Yishui spring ,Yishui,Shandong show that the precipitation is the greatest disturbance that affects the variation of the radon in Yishui spring. Because there exists "memory" lag influence in the disturbance, it is difficult to completely removed this influence by ordinary relative analysis. However, it can be better removed using convolution integral method. The variation characteristics of the interval probability of the radon in Yishui spring before and after Heze M\-S 5.9 earthquake are analyzed. The relationship is discussed between the variations of the interval probability and the regional stress field adjustment.
